why is light called an electromagnetic wave??what does it have to do with electricity and magnetism?
Light is a form of electromagnetic radiation that is visible to the human eye. It is made up of particles called photons that have both wave-like and particle-like properties.
The speed of light in a vacuum is approximately 299,792,458 meters per second, or 186,282 miles per second. This is the fastest speed that anything can travel in the universe.
Light can interact with matter in three ways: reflection, transmission, and absorption. Reflection occurs when light bounces off a surface, transmission occurs when light passes through a material, and absorption occurs when light is absorbed and converted into other forms of energy.
The electromagnetic spectrum is the range of frequencies of electromagnetic radiation, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Visible light makes up a small portion of the spectrum, with shorter wavelengths appearing blue and longer wavelengths appearing red.
Light is used in a wide variety of technologies and everyday life, including in communication (such as fiber optic cables), medicine (such as lasers in surgery), and entertainment (such as television and cinema). It is also essential for photosynthesis in plants and plays a crucial role in our vision and perception of the world around us.
